Page 2 of 30 Warp knitted structure: lengthwise (warp wise) direction of loops is called warp knitted structure. Mesh fabric: ing fabric, look like a mosquito net use in short garments. Power net: use in Hajack lamp. Weft knitted structure: widthwise (weft wise) direction of loops is called weft knitted structure. Wales: vertical columns of loop are called Wales Course: horizontal raw of loop is called course. Types of knitting m/c:. Circular knitting m/c: Needles are arranged in circular way that’s why it is called circular knitting m/c. It has two needle beds. One is cylinder (vertical needles) Another is dial (horizontal needles) Dia: maximum circle distance in a circle is called dia. Two types of dia small dia (for socks) large dia (cutting fabric – lacoste/pique) Gauge: It means thickness. no. of gauge Fine gauge : T-shirt (24g, 40g) Course gauge: sweater (3g, 5g) Higher the gauge finer the knit, lower the gauge courser the knit. Flat bed Knitting m/c: Needles are arranged in flat way that’s why it is called flat bed knitting m/c. It has two needle beds. -Technical front (T.F) - Technical back ( T.B) It is also called Jacquard m/c. Integrated garments: without any stitch or linking in garments. without any , seamless garments.
Page 3 of 30 Shem seiki: Shem seiki is first producer of whole garments in Japan. Company name is also known as brand. -Ladies shirt is known as ladies blows. - Heavy knitwear means sweater. Why it is called fully fashion? Fully fashion: Fully fashion is a method / technique of shaping a knitted structure by increasing or decreasing the number of needles or wales. In the fully fashion there is no fabric formats. Just it is made by increasing or decreasing the shape of end product, increasing or decreasing of needles. Advantages of fully fashion: -
we can produce zero(less) wastage garments. Less manpower. we can produce quality garments/sealed garments.
Disadvantage:
Textile fiber: anything that can be garments/originated from fiber. In narrow sense: Textile means – fiber to fabric production. ie fiber
yarn
In greater sense: fiber clothing Fibers are chemical/natural structure that can be spun into yarn. Basic requirements for fibers:
Based on sourcing: Textile fiber Natural Animal (wool) Plant/vegetable (cotton)
Chemical made Acrylic
Fiber: any types of substance but the length and thickness ratio is very high.

1. Why we weight the yarn? If not weight the yarn then worker miss use the yarn. In distribution room blog/protection because any worker could not entered the distribution room.
Fully fashion m/c - Less manpower - Quantity -Design low Knitting process is depend on design chart – Heart of the sweater production operator could not idea about actual design chart .So they could not say how to design it. They learn if with experience not scientific way. 7 gage: - 7 needles exist in per inch. Fabric fault in fully fashion: 1. Hole 2. Laddering 3. Ply mistake --- yarn broken. 4. Why we women worker in mending section? Here is poor salary and women are expert in mending and they have biological .

Tremble drying m/c. Boiler ----- Steam iron. Different types of stitches / Design used in fully fashion Basic category: 1. Jersey stitch Fancy category 2. Rib stitch -- shaker / Half cardigan stitch. 3. Double jersey --- Full cardigan stitch Cables:--Milano stitch 1. Normal -- Tuck stitch 2. Fancy --printal stitch 3. Butterfly -- Zigzag stitch -- Drop knit stitch . Diamond:1. Normal 2. Fancy Stitch – An intermeshed loop. Describes different types of stitches / Design -----Jersey / Single jersey/single knit / plain knit / basic knit etc. This is very basic knitting construction .It’s a single beded structure .The needle diagram of jersey is -----------The stitch diagram is -----It can produce both in flat bed 4 circular bed m/roperties of Jersey stitch:Appearance: - In single Jersey both side are different in appearance. Out look:T/M: V Shape stitch /jersey stitch. T/B: Semi circle stitch /Are stitch. -
Edge curling : it curls T/B to t/B T/B to T/B in width wise Length wise wilts wise Strength: - Tightness and looseness activity. Yarn tension – T/F to T/B G curl -Unbalanced fabric because back side no needle. Carling – so worker take time to linking and producing extra time.
How to reduce the curly:-
Page 12 of 30 1. After knitting and before sewing /linking by using parching. (Light knit circular knit swach) 2. Use folder /attachment 3. Use standard m/c Dimensional stability: - Because of single jersey dimensional stability in poor. S.J garments do not washable. How to reduce the dimensional stability? 1. To increase loop density 2. Apply resin finish chemical resin use properties shaf t - Soft ness - Estability / elasticity. Elasticity:-Length and width wise elasticity is same because course and wales wise loop length almost same. Unraveled: we can unroalled this structure in both side. How ladering defect create – 1. Needle head broken. 2. Loose tension. 3. Knot in the yarn. Rib knitted structure:- The word rib derives from animal rib. This is a double beded structure. The needles heads are not facing directly each other. There are various types of rib knitted structure. But very common structure is 1x1 & 2x2 rib; above3x3, 4x4 etc are known as fancy rib. But 6x6 rib is known as specially Derby rib. The needle diagram of 1x1 ribs and stitches diagram of 1x1 The needle bed of 2x2 and stitch is can produce both flat bed and circular bed knitting m/c. Appearance: - Same in appearance. -semi circle loop can be observed between in v shape. Edge curling: Rib structure does not curl at the edge. Its balanced structure. Dimensional stability:-Dimensional stability is good. Elasticity:-width wise direction is high than that of length wise.
Why width wise elasticity high? -Semi circle width is high, so width wise elasticity high. Unraveled from close it only.
Page 13 of 30 Density: - Density is high in temperature in single jersey. End use : - waist band, collar, cuff or total sweater. we can use by rib fabric. High rib – under garments, because elasticity and comfort ability. Similarities between the single jersey and rib Structure. 1. we can produce the Single Jersey and Rib fabric in similar flat bed and circular bed knitting m/c. 2. Both types fabrics are knitted structure. 3. Both fabrics are mend able. 4. created by loop formation.
Double jersey / Interlock/ Double faced fabric: If the plain stitches are one bedded, the other fabric structure is known as double jersey / interlock. It’s double bedded fabric, can produce both in flat bed & circular bed knitting m/c. The needle diagram of double jersey is ------and the stitch diagram is -----It is called tight knitted. Theoretically needle heads are kept face to face but practically needle heads are not face to face. It stay little bit in angle. Properties and appearance. 1. Both side similar. 2. Curl: Double jersey does not curl because it very tight knitted fabric. 3. Dimensional stability good.. 4. Unraveled : Same as rib. 5. Elasticity : Poor 6. Defecting: It laddering occurs. We can’t mending like rib & jersey. 7. Density : Density high because both side needles are active. Thickness & elasticity consider while identifying double jersey.
Page 14 of 30 End use: Sweater Gents & ladies wear Light knit. Sports wear ( suet absorbency high, dimensional stability high ) Ladies shirt.
Similarities between D/j and rib : Basic knit Both can made in flat bed circular bed m/c. Both fabrics both side appearance same Does not use. Dimensional stability good. Unraveled: Both are same. Difference between D/j & Rib 1. Needle diagram – 2. Stitch diagram 3. elasticity -

Page 15 of 30 Notation for knitted structure :
The symbol which represent different types of loops are called notations. There are two types of symbols. We use to identify different structure like Indicate technical face (v) loop Indicate technical back loop. So for single jersey Impotency : 1. Language variation avoided 2. Different name confliction avoidance. 3. Loop drawing is difficult and time consuming to avoid this problem

Fashioning (Design chart/pattern chart) calculation for fully fashion knitwear
Page 23 of 30
What is design: Design is a creative indexer to solve a problem. What is design chart: Design chart for a garment is a visual written instruction Design chart produce in two methods: a) Out line method b) Graphical method What is the basic requirement to calculation design chart? a) b) c)
Size specification (Measurement) Gage type Weight of the garments
Pattern: Shape create by increasing or decreasing size that is called pattern. Art: Art is the blue print of the design. Design: Actual shape of the thing. Swatch: Small part of the fabric. Tension: Tight are looseness of the yarn is called tension.
Buyer’s required weight accordingly tension setup. But in seven gage m/c 8 or 6 needle coming for tension. So tension selection in important because it is related to quality. Swatch identification:
